I present the poor man’s diamond plate sharpening system. I first came up with this idea based on a blog I read where a guy compared his DMT stones to the inexpensive diamond stones from China. For him, and I as well, they hold up fine for hobby use. And by hobby use, I mean I have sharpened well over 100 times on these and they are just now breaking in a bit. These have given me excellent results for everything I have thrown at it (chisels, plane irons, knives, etc).
One of the biggest hurdles was finding the thin diamond plates in a large enough size. I found them from ebay. The dimension of the plates are: 170mm x 75 mm /6.69″ x 2.95″. That’s close enough to the DMT stones dimensions. It allows you the width of a plane iron without having to angle it. I got 3 of them in grit sizes 240, 500 and 1200. For around $8 each ($24 total shipped)
I then found 1/4″ X 3″ ALUMINUM 6061 FLAT BAR 7″ long from ebay as well. This would make the overall thickness very close to the original DMT stones. I got 4 of them for $14 shipped.
So at this point I am out a whopping $38 for 3 diamond stones that are very close to the overall dimensions of the EZE-Lap ($50 each) or DMT stones ($55 each). You do the math.
I then simply glued the diamond plates to the aluminum bar stock with gorilla glue and clamped them for 24 hours. I figure if these ever do need replacing, can simply pop the old ones off, clean the aluminum bar and glue the new ones in place. I then found some poplar at Lowes (1 x 12 x 24) it was damaged on one end so I got for like $6. I then used Paul’s blog entry on making the diamond plate stone holder https://paulsellers.com/2013/04/making-my-sharpening-plate-holder/
All in all I got 3 diamond plates and it’s holder for $44. That’s quite a bit less than just one of the other guys. Here are the other thousand words I could say.
